Due to the high perishability of strawberries and their limited shelf life, the present study with the aim of evaluating the effect of foliar application of amino acid and seaweed extract on quantitative and qualitative as well as potharvest life of Camarosa strawberries, was conducted in a factorial in complete randomized block design in 2020- 2021. Foliar application of amino acid and seaweed extract (1 and 2 g L-1) was carried out during three stages; before flowering, during flowering and fruit formation. After three- quarters of the fruit’s surface turned red, fruits were harvested and stored at 0±1°C for 15 days. Quantitative and qualitative characteristics of stored fruits were measured every five days. The results showed that the strawberries sprayed with amino acid had higher quality characteristics due to lower weight loss and acidity during storage. Also, treatment with amino acid increased the soluble solids, sugar compounds, vitamin C, anthocyanins, flavonoids, total phenols, and antioxidant activity of fruits by 1.5-2.5 times compared to the control. In conclusion, the application of 1 g L-1 of amino acid as well as 1 g L-1 of seaweed extract had the greatest effect in increasing the fruit yield, maintaining and improving the storage characteristics of the Camarosa strawberry.
